À propos of not much, other than overexposure, a word of warning to all D700 users.
I was surprised to find some burned out highlights on a few files made the other day during a shoot along with Chris F; I had secretly wondered whether he was electrostically charged, or something, and had affected the camera's innards, but no, I think I discovered the problem: when doing vertical shots, it turns out that it's terribly easy both to hold one's index finger in the vicinity of the shutter release and inadvertently press the exposure compensation button near it at the same time, whilst scrolling the control wheel at the rear of the camera with the thumb in order to change the shutter speed. Ironic, really, as I was using an electronic cable release. I was exposing everythng at +1 (no, not that +1).
This never happened to me before; I hope it doesn't again.
